OEM ThrottleBody -> Mild upgrade

[PocketRocket]

Hi guys, i'm doing a very mild performance for my car, im driving a 4G15P,Siemens,VDO and would like to change a bigger throttle body from OEM.

Q1 - what TB can i get to Plug & Play to the original base without modifying anything?

Q2 - what is an advisable size of TB to get? if not mistaken, my OEM one is slightly under 2.5 inch and im not too sure cuz it din occur to me till now

simple question hope i get simple answers

don't. u'll be getting nothing. since u stated that u are DOING a mild performance, i presume ur engine is still stock.

unless u did some porting, balancing internal parts then u might think about over sizing your TB

if want to change also what throttle body can fit ur siemen 4g15 engine..

 

[UnicornSpeed]

can use 4g93 vdo tb

93TB + Port N Polish + 272cam = like seanlee's car

no point bro. if ur tb is bigger, ur intake manifold is still the same size, instead of gaining u will lose out. this is due to the "step effect" or so they call it. (bigger TB, small IM = air flow being restricted)

only diff u will feel is ur pocket getting lighter..

unless u port ur intake manifold to match exactly, and get a set of cams = wah lah!

Full tank = 340-360km...with a light foot.
